Dock & window switching issues in Fedora 35

[Matt Morgan]

Hi. I recently upgraded to Fedora 35. I would like to change two behaviors
back to what I had before:

1) when I mouse up to the hot corner, the application dock is now at the
bottom of the screen. How can I get the dock to position itself vertically
along the left side of the screen? I've tried a few gnome extensions but
none I can find does that (except when floating the dock, which is not what
I want).

2) When I alt-tab I can get an application list, but not a window list
(e.g. if Thunderbird has two windows open, I see one entry for Thunderbird,
not two). I think I used to use an extension called "Alternate Alt-tab" to
change this, but that extension doesn't seem to be available for F35.

Bonus question: I can't find a weather extension for gnome anymore. The one
I used to use was called "OpenWeather," I think. Is there a substitute?

Thanks,
Matt
